The corridor
Detroit Metropolitan Airport in Romulus handled 354,581,419 lb of cargo in 2025. Amazon's DTW1 fulfillment center in Romulus opened in 2018 and employs about 1,600 people, and Kroger built a $95 million automated fulfillment center there in 2021. Canton Township's 2024 top employers include Sysco Detroit (373) and Amazon (300). Novi's include Ryder (660) and Lineage Logistics (655).
We name them to describe the freight of the corridor, not as customers. A warehouse of that kind receives inbound in gaylords and has to clear them. It also needs boxes for returns, consolidation and internal moves. Both sides of the same dock.
Selling what arrives
Inbound freight leaves single-trip gaylords. Dry and square is Grade A. Stage them, knock down what you can, and send the footprint, wall count and how many. See clearing empties. Wet or crushed boxes belong in recycling.
Buying what you need
| Use | Usual box | Why |
|---|---|---|
| Returns consolidation | 48 x 40 x 36 in, 2- or 3-wall, Grade B | Moderate loads, internal use |
| Cross-dock moves | 48 x 40 x 48 in, tall | Light, bulky freight |
| Scrap film and cardboard collection | Grade C of any size | One-way internal use |
| Kitting and small parts | 40 x 30 x 30 in | Hand-fed lines |
Cold storage and other conditions
Novi is home to cold storage. Cold makes board stiffer and more brittle, adhesives can lose effectiveness, and moving corrugated between temperature zones can cause condensation that weakens it. The corrugated trade advises storing it in heated areas above 55 degrees Fahrenheit. If your boxes live in a cold building, say so.
